We don't see a lot of Exynos chips shipping in Samsung phones in the US, but the rest of the world is swimming in devices running Samsung's in-house ARM chip. The Exynos 5 Octa (5410) debuted in the Galaxy S4, and now an updated version of that chip known internally as the Exynos 5420 has been officially announced.

Like the older Exynos 5 Octa chip, the 5420 has eight total cores that leverage ARM's big.LITTLE design.

It's not much of a secret that the Samsung Exynos process is one of the fastest dual-core mobile chips on the planet. Sammy announced the blazing fast evolution of its flagship processor this morning, and it's said to be twice as fast as the current chip. It's still dual-core and clocks in at 2GHz, only a slight bump up from the current speed.
